I also encountered the same problem
Hope to specify PVC binding to the corresponding directory
Will be fixed in 0.23.4. There is a workaround in the current version, but better not to use it, it will be deprecated.
Please let me know after you've fixed it. Thank you very much
Approximately when can this be fix
I run into the same issue. What do we need to do in the meantime to get things working? I just need to get CHK working with my CHI and I don't want to wait a few days or longer until a fix gets released. Ideally I get this working today with whatever workarounds are needed for now.

For original issue - probably we should have working & better example in https://github.com/Altinity/clickhouse-operator/tree/master/docs/chk-examples
0.24.0 works properly with volumeClaimTemplates check https://github.com/Altinity/clickhouse-operator/tree/0.24.0/docs/chk-examples/
migration from old schema 1 statesfulset with multiple replicas per one kind: ClickHouseKeeperInstallation
to separate statefulset with one replica for each replica from kind: ClickHouseKeeperInstallation
still in development, so wait when 0.24.0 will complete
We are trying to migrate our own keeper config to CHK, but it seems the PVC template is not taking into account. By quickly scan the code, it seems when creating CHK, it only cares about how many keeper volumes are declared instead of the content of the pvc? At least in our case, k8s complains about "both-paths" not found.
